Magnetos: several things you should know

Today the remarkable electric Tesla accelerates from zero to 100mph in 8 seconds and runs 250 miles on a charge, such is the progress from industrialist Elon Musk’s unique car company. A century ago the magneto was the star at the rich core of our motive lives.

Cooling fix for power steering systems and automatic transmissions

Cooling fix for power steering systems and automatic transmissions

Kennesaw, GA: KRC believes they have a new contender for fluid-cooling honors. Earlier this year they expanded their horizons when they introduced a promising new power steering fluid that withstands repeated high temperature usage. Now they are launching a new all-aluminum furnace-brazed fluid cooler for power steering systems and automatic transmissions. It promises to demonstrate impressive heat dissipation, presenting itself as 40 percent more effective than regular fin-tube or  spline-fin coolers. Combining micro fins with serpentine fins Impressive heat dissipation can be elusive. But by channeling the fluid through multiple internal fins located within four flat-sided oval extrusions, KRC succeeded in reducing fluid temperatures by 22F degrees. The temperature difference is measure between fluid entering the inlet port and exiting the outlet port. Furthermore, as the heat transfers through the micro fins and the extrusion walls, its dissipation is hastened when it reaches a dense maze of serpentine fins. Attached to the external surfaces by a technology known as furnace brazing the serpentine fins, though almost invisible to the naked eye are themselves festooned with a multitude of tiny louvered fins. At the rear of the cooler a vertical plate runs its length with angled slots and the letters KRC notched out. Their objective, particularly the angled slots, is to create turbulence. The turbulence generates a negative pressure that disrupts the air flow, which further improves cooling performance. Importantly, the cooler exhibits minimum flow restriction, hence a minimum pressure-drop that further aids cooling performance. How hot oil travels through a cooler without losing heat! Oil, when heated, builds an insulation layer between the internal surface of the tube and...
Ford of 1910: changes to make you ponder

Ford of 1910: changes to make you ponder

Data loosely compiled by Martha Maglone, April 6, 2015: For this Ford of 1910 only 144 miles of paved roads existed in this country. In fact, only 8,000 cars existed in the entire nation, the maximum speed limit in most cities was 10mph and fuel was available from drug stores only. More importantly life expectancy for men was 47 years. In 1910 the average US wage was 22 cents per hour and only 14 percent of homes had a bathtub and 8 percent a telephone. The average US worker made between $200 and $400 per year. A competent accountant could expect to earn $2,000 per year, a dentist $2,500 per year, a veterinarian between $1,500 and $4,000 per year, and a mechanical engineer about $5,000 per year. In 1910 more than 95 percent of all births took place at home. Ninety percent of all doctors had no college education! Instead, they attended so-called medical schools, many of which were condemned by both press and government as ‘substandard.’ In 1910 eggs cost fourteen cents a dozen and sugar and coffee four and fifteen cents a pound respectively. Most women washed their hair only once a month, and used Borax or egg yolks for shampoo. There was no such thing as under-arm deodorant or tooth paste. Canada, warm-heartedly, passed a law that prohibited poor people from entering their country for any reason. In 1910 the five leading causes of death were: 1. Pneumonia and influenza 2. Tuberculosis 3. Diarrhea 4. Heart disease 5. Stroke In 1910 crossword puzzles, canned beer, and iced tea hadn’t yet been invented—neither had Mother’s Day nor Father’s Day....
Fancy a quick lap of the Silverstone GP circuit?

Fancy a quick lap of the Silverstone GP circuit?

As Radical’s latest RXC Spyder prototype drew closer to completion, track testing is imminent. Now spring and antiroll bar rates are settled and the damper settings, roll centers and Ackerman angles operating at their optimum, you’ll enjoy sweeping through those ancient curves of Copse, Abbey, Maggott’s and Beckett’s at speeds approaching 125mph. Watch the video: The new Radical RXC Spyder is powered by a 2.9 liter V8. It produces 460hp, weighs a mere 200lbs and transmits its power through an ingenious 7-speed transverse transmission.

New Edelbrock Rollin’ Thunder Camshaft For Small-Block Chevrolet Engines

New Edelbrock Rollin’ Thunder Camshaft For Small-Block Chevrolet Engines

TORRANCE, CA (April 2, 2015) – Edelbrock has introduced a new Rollin’ Thunder camshaft for small-block Chevrolet engines. Designed to improve horsepower and torque, it produces an evocative idle sound yet provides sufficient vacuum. Rollin’ Thunder camshafts feature more aggressive lift profiles than conventional flat-tappet hydraulic cams, without excessive valve overlap that can compromise low rpm driveability. The new Rollin’ Thunder camshaft (#2231) is designed specifically for use with 1957-86 Chevrolet 283-400 V8 engines. It features a unique profile that will provide sufficient vacuum at idle for power brakes and other vacuum-powered accessories. In addition it includes assembly lube and instructions (lifters sold separately). During testing, this camshaft produced 460 HP and 460 ft-lb of torque when matched with a Performer RPM intake manifold (#7516), a Thunder Series AVS carburetor (#1813) and Performer RPM E-Tec cylinder heads (#60985) on an Edelbrock 383 crate engine. Features Include Rollin’ Thunder camshafts are designed for optimum power from 1,500 to 6,500 rpm Rollin’ Thunder camshaft (#2231) is designed for use with 1957-86 Chevrolet 283-400 V8 engines It produced 460 HP and 460 ft-lb of torque on an Edelbrock 383 c.i.d. crate engine Features aggressive profiles that will also provide excellent performance with sufficient vacuum at idle for power brakes and other vacuum-powered accessories Includes camshaft, assembly lube and instructions.
